AI Technical Summary
When using signals generated based on OOK waveforms for wake-up, existing technologies require the introduction of two indicator fields to ensure energy efficiency, which increases bit overhead. How to achieve energy efficiency without increasing the number of indicator fields is an urgent problem to be solved.
By receiving or transmitting a signal generated based on the On/Off Keying (OOK) waveform on at least one first serving cell, the second device is instructed to turn on or off the timer on the second serving cell, thereby controlling whether the PDCCH is being listened to or not, and avoiding the introduction of an additional indication field.
When waking up using a signal generated from an OOK waveform, energy saving is achieved through a single signal indication, avoiding additional bit overhead.

Abstract
Description
Signal transmission method, device and equipment
[0001] The present disclosure claims priority to the Chinese patent application No. 202411382161.1, filed on September 30, 2024, and entitled "Signal transmission method, device and equipment", the whole content of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present disclosure relates to the field of communication technology, in particular to a signal transmission method, device and equipment. BACKGROUND
[0003] Currently, the downlink control information with CRC scrambled by PS-RNTI (DCP) can only be received on the primary cell (Pcell), and the wake-up indication field acts on all active serving cells. The signal generated based on the on-off keying (OOK) waveform (for example, the low power wake-up signal (LP-WUS)) is not a physical downlink control channel (PDCCH), so it can be received on the dormant bandwidth part (dormant BWP) of the secondary cell (Scell) according to the related protocol. The related DCP mechanism indicates that the terminal starts the timer on all cells according to the 1bit indication field, and then indicates the BWP switching of the terminal on the Scell according to the 0-5bit Scell dormancy indication field, so as to ensure the energy saving effect. It can be seen that in order to ensure the energy saving effect, the DCP introduces two indication fields, i.e. the 1bit wake-up indication field and the 0-5bit Scell dormancy indication field. If the signal generated based on the OOK waveform is used for wake-up according to the related mechanism, two indication fields also need to be introduced, which increases the bit overhead.

[0044] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of, rather than all of, the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.
[0045] The terms "first", "second", and the like in the specification and claims of the present disclosure are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in other sequences than those illustrated or described herein. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product, or device.
[0046] The term "and / or" used in the embodiments of the present disclosure describes an association relationship of associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it. The term "multiple" in the embodiments of the present disclosure means two or more, and other quantifiers are similar.
[0047] In the embodiments of the present disclosure, the word "exemplary" or "for example" is used to represent an example, illustration, or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the word "exemplary" or "for example" is intended to present the relevant concept in a specific manner.
[0048] The related concepts mentioned in the present disclosure will be briefly described as follows.
[0049] I. Carrier aggregation (CA) technology
[0050] Similar to long term evolution (LTE), NR also adopts CA technology to greatly improve the system transmission rate. Each carrier participating in CA is called a carrier component (CC). Among them, the primary cell (Pcell) is used to carry signaling and manage other carriers. The secondary cell (Scell) is used to expand the bandwidth to enhance the rate, and the Pcell can decide when to increase and delete.
[0051] II. Scell energy saving
[0052] When there is no data transmission, the Scell can be deactivated by Medium Access Control-Control Element (MAC-CE) for energy saving. But it is a long process to activate the Scell, which corresponds to a large transmission delay and terminal energy consumption. Therefore, the dormant downlink bandwidth part (dormant DL BWP) is introduced for the Scell. The main purpose of adding the dormant DL BWP is to save power. When the data traffic is not large, the BWP on the Scell can be temporarily switched to the dormant BWP, and the secondary carrier does not need to be deactivated. Compared with the method of adding or deactivating the secondary carrier by Radio Resource Control (RRC), the Scell can enter the uplink and downlink data transmission state more quickly. The terminal does not need to detect the Physical downlink control channel (PDCCH) under the dormant BWP, only needs to do some measurement operations to maintain the link performance, and can maximize the energy consumption of the Scell.
[0053] III. Scell dormancy indication
[0054] Currently, the Scell can be switched between the dormant BWP and the non-dormant BWP by the Downlink Control Information (DCI).
[0055] The DCI indicating the Scell to be switched between the dormant BWP and the non-dormant BWP can be one of the following:
[0056] indicated by the DCI format 0_1 / 0_3 / 1_1 / 1_3 in the ACTIVE time;
[0057] indicated by the DCI format 2_6 (DCP) outside the ACTIVE time.
[0058] IV. Connected-Discontinuous Reception (C-DRX)
[0059] DRX is a function introduced by user equipment (UE) for power saving, configured by RRC layer. In connected state, if RRC layer configures MAC layer with DRX function, UE can monitor PDCCH intermittently in physical layer; otherwise, UE must continuously monitor PDCCH. The configuration of DRX is applied to all active serving cells, i.e. when in radio resource control connected state (RRC_CONNECTED), if DRX is configured for all active serving cells, MAC entity can use DRX operation to discontinuously monitor PDCCH.
[0060] V. DCI format 2_6
[0061] DCI scrambled by paging system radio network temporary identifier (PS-RNTI) is called power saving DCI (DCP), which has two indication fields, wake-up indication and Scell dormancy indication. When DCP indicates wake-up, ACITVE time is turned on, and Pcell receives PDCCH according to DRX. Further according to Scell dormancy indication, dormant BWP indication is performed for activated Scell. If activated BWP is indicated as dormant BWP, PDCCH monitoring is not performed, and if activated BWP is indicated as normal BWP, PDCCH monitoring is performed according to DRX.
[0062] Considering that PDCCH cannot be received on Pcell after switching to dormant BWP and data retransmission is performed, Rel-16 only supports transmission of DCI format 2_6 on Pcell.
[0063] VI. Background of LP-WUS / WUR project
[0064] Rel-18 proposes the concept of low power wake-up signal (LP-WUS) and low power wake-up receiver (LP-WUR, LR). When there is data transmission, the terminal receives LP-WUS signal through LP-WUR to activate main radio (MR) to wake up from ultra-deep sleep state to receive data; when there is no data transmission, the MR is turned off, which can greatly achieve terminal energy saving.
[0065] Embodiments of the present disclosure are described below with reference to the accompanying drawings. The signal transmission method, apparatus and device provided by the embodiments of the present disclosure can be applied in a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as 5G system), and those skilled in the art can understand that the 5G NR system is only an example and is not limited.
[0066] In some embodiments, the network system to which the embodiments of the present disclosure can be applied includes a user terminal and a base station. The user terminal can be a user equipment (User Equipment, UE), for example, a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device, and it should be noted that the specific type of user terminal is not limited in the embodiments of the present disclosure. The base station can be a 5G and later version base station (for example, gNB, 5G NR NB), or a base station in other communication systems, or a node B, and it should be noted that the embodiments of the present disclosure only take the 5G base station as an example, but the specific type of base station is not limited.
[0067] The embodiments of the present disclosure provide a signal transmission method, apparatus and device to ensure energy saving effect when using a signal generated based on an OOK waveform for wake-up.
[0068] The method and the apparatus are based on the same application concept. Since the principles of the method and the apparatus for solving the problem are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be described.
[0069] As shown in FIG. 1, the embodiments of the present disclosure provide a signal transmission method, executed by a first device, comprising:
[0070] In step S101, a first signal is received on at least one first service cell, the first signal being used to indicate that a second device starts or does not start a timer on a second service cell, and the second service cell includes one or more of the activated service cells configured for the second device;
[0071] The timer is not started, and the second device does not listen to the PDCCH; the timer is started, and the second device listens to the PDCCH or does not listen to the PDCCH; the first signal is generated based on an on-off keying (OOK) waveform; the first device is a device with a first receiving capability, and the second device is a device with a second receiving capability, and the second receiving capability is higher than the first receiving capability.
[0072] In some embodiments, the first receiving capability mentioned in the embodiments of the present disclosure can be the capability of only detecting the signal generated by the OOK waveform, and the second receiving capability can be the capability of not only detecting the signal generated by the OOK waveform but also detecting the signal generated by other manners, for example, the first device can be an LP-WUR, and the second device can be an MR; in some embodiments, the first device and the second device can be simultaneously arranged in the same device or independently arranged in different devices.
[0073] It should be noted that the embodiments of the present disclosure are applicable to the CA scenario, that is, the application scenario in which the first device and the second device are configured with one primary cell and at least one secondary cell.
[0074] In some embodiments, the first signal mentioned in the embodiments of the present disclosure can be an LP-WUS, and of course, the first signal mentioned in the embodiments of the present disclosure can also be other signals generated based on the OOK waveform and used for indicating the second device to start or not to start the timer on the second serving cell; in some embodiments, the first signal is a dedicated receiving signal of the first device.
[0075] It should be noted that by receiving, on at least one first serving cell, the signal used for indicating the second device to start or not to start the timer on one or more of the activated serving cells configured for the second device, the indication of the PDCCH listening or not listening can be performed only by the first signal, without introducing other indication fields, so that when the signal generated based on the OOK waveform is used for wake-up, the purpose of ensuring the energy saving effect can be achieved.
[0076] In some embodiments, the activated serving cell mentioned in the embodiments of the present disclosure can also be referred to as an activated serving cell.

[0078] In some embodiments, the timer mentioned in the disclosure can be a discontinuous reception duration timer (drx-onDurationTimer), a discontinuous reception inactivity timer (drx-InactivityTimer), or a newly introduced timer in the disclosure.
[0079] In some embodiments, in an implementation, for the first device, the first serving cell is determined by at least one of the following:
[0080] A11, agreement of protocol;
[0081] For example, the agreement of protocol can indicate that the first serving cell is a primary cell or a secondary cell.
[0082] A12, indication of network device;
[0083] For example, the network device can indicate the first serving cell by MAC-CE, high layer parameter, or DCI.
[0084] In some embodiments, in the case that the first signal is an LP-WUS, the high layer parameter can be, for example, a LP-WUS serving cell reception (ServingcellReception_LP-WUS) parameter. In some embodiments, the DCI mentioned in the embodiments of the disclosure can be a newly introduced DCI, or an existing DCI, that is, the indication of the first serving cell is multiplexed into the existing DCI.
[0085] In this case, the terminal determines the first serving cell according to the indication of the network device, which can be a primary cell or a secondary cell.

[0090] In some embodiments, the reception capability of the first device can include, for example, a first type of reception capability and a second type of reception capability; in some embodiments, the first type of reception capability indicates a weaker reception capability, for example, only receiving signals at a fixed frequency point or a small range of frequency domain; the second type of reception capability indicates a stronger reception capability, for example, receiving signals on all active serving cells.
[0091] In some embodiments, the first serving cell corresponding to different types of receiving capabilities can be pre-set or pre-agreed, for example, in the case that the first device is of the first type of receiving capability, the first serving cell can be the primary cell; in the case that the first device is of the second type of receiving capability, the first serving cell can be the default cell, or the primary cell, the secondary cell or the secondary cell group.

[0094] As shown in FIG. 2, the first signal received by the first device on one activated serving cell can indicate that the second device starts or does not start a timer (i.e., monitors or does not monitor PDCCH) on all activated serving cells.
[0095] Application scenario two, the second serving cell includes at least one activated serving cell among the activated serving cells configured for the second device;
[0096] As shown in FIG. 3, the first signal received by the first device on one cell can indicate that the second device starts or does not start a timer (i.e., monitors or does not monitor PDCCH) on part of the activated serving cells, for example, the first signal sent at time 1 indicates that the second device monitors PDCCH on the primary cell, the first signal sent at time 2 indicates that the second device monitors PDCCH on secondary cell 1 and secondary cell 3, and the first signal sent at time 3 indicates that the second device monitors PDCCH on secondary cell 2.

[0098] As shown in FIG. 4, the first signal received by the first device on one cell can only indicate that the second device starts or does not start a timer (i.e., monitors or does not monitor PDCCH) on the activated serving cell, that is, the first device needs to receive the first signal on several activated serving cells when the second device has several activated serving cells.
[0099] In some embodiments, after receiving the first signal, the first device needs to send an indication to the second device, which indicates that the second device starts or does not start a timer on the second serving cell.
[0100] In some embodiments, the method further comprises, in an implementation:
[0101] decoding the first signal according to the configuration parameter to obtain indication information, the indication information being used to indicate whether to start or not to start a timer on a second serving cell by the second device;
[0102] Further, the first device sends the indication information to the second device, and the second device performs corresponding behavior based on the indication information sent by the first device, i.e., starting or not starting the timer (which can also be understood as monitoring or not monitoring PDCCH).

[0107] B121, indicating whether to start the timer by a bit map, wherein one bit in the bit map is used to indicate whether to start the timer on the second serving cell by one second device;
[0108] It should be noted that in this case, it can be understood that there is only one bit in the bit map, and this bit is used to indicate that the execution of the timer corresponding to all activated serving cells in the second serving cell is the same, for example, when the bit value is 0, it indicates that the second device does not start the timer on the second serving cell, and when the bit value is 1, it indicates that the second device starts the timer on the second serving cell; or, when the bit value is 1, it indicates that the second device does not start the timer on the second serving cell, and when the bit value is 0, it indicates that the second device starts the timer on the second serving cell.
[0109] B122, indicating whether to start the timer by a code point, wherein the value of one code point is used to indicate whether to start the timer on the second serving cell by the second device;
[0110] It should be noted that this case can be understood as that there is a code point in the first signal, and the value of the code point is used to indicate that the execution of the timer corresponding to all activated serving cells in the second serving cell is the same, for example, when the value of the code point is 00, it indicates that the second device does not start the timer on the second serving cell, and when the value of the code point is 11, it indicates that the second device starts the timer on the second serving cell; or, when the bit value is 11, it indicates that the second device does not start the timer on the second serving cell, and when the bit value is 00, it indicates that the second device starts the timer on the second serving cell.
[0111] In some embodiments, in the case that the second serving cell includes at least one activated serving cell configured for the second device, the indication manner includes one of the following in an implementation:
[0112] B1201, indicating, by a bit map or a code point, whether the second device starts the timer on all activated serving cells included in the second serving cell at the same time.
[0113] It should be noted that this case can be understood as that the execution of the timer corresponding to all activated serving cells in the second serving cell is indicated by a bit map or a code point.
[0114] For example, when the bit value is 0, it indicates that the second device does not start the timer on the second serving cell, and when the bit value is 1, it indicates that the second device starts the timer on the second serving cell.
[0115] For example, when the value of the code point is 00, it indicates that the second device does not start the timer on the second serving cell, and when the value of the code point is 11, it indicates that the second device starts the timer on the second serving cell.
[0116] In some embodiments, the code point can have a mapping relationship with a code or a sequence; for example, the code can be Manchester coding; the type of the sequence can be a walsh sequence, a gold sequence, an m sequence, etc., and the sequence generation can be related to at least one of the first device identifier, the cell identifier, and the first signal index.
[0117] B1202, indicating, by a bit map or a code point, whether the second device starts the timer on the activated serving cell included in the second serving cell.
[0118] In some embodiments, this case can be understood as that the execution of the timer corresponding to different activated serving cells in the second serving cell is indicated by a bit map or a code point.
[0119] In some embodiments, in the case that whether the second device starts the timer on the active serving cell included in the second serving cell is indicated by the bit map, the first device can listen to the bit position of the corresponding active serving cell according to the listening position parameter; in some embodiments, the listening position parameter is used to indicate the information bit position that the first device needs to listen to in the first signal, and the listening position parameter can be a bit position, an OFDM symbol index, or an OOK symbol index.
[0120] In some embodiments, in the case that whether the second device starts the timer on the active serving cell included in the second serving cell is indicated by the code point, the relationship between the value of the code point and whether the second device starts the timer on the second serving cell satisfies at least one of the following:
[0121] B12021, the mapping relationship between the value of the code point and the active serving cell is determined based on the mapping relationship, and the mapping relationship between the value of the code point and the active serving cell can be indicated by one mapping relationship table or multiple mapping relationship tables.
[0122] For example, there are two levels of indications in a first signal, each level of indication corresponds to a mapping relationship table, the first level of indication corresponds to the mapping relationship table shown in Table 1, the second level of indication corresponds to the mapping relationship table shown in Table 2, and the mapping relationship table includes the value of the code point, the sequence index, and the cell index.
[0123] Table 1: Mapping relationship table corresponding to first level of indication
[0124] Table 2: Mapping relationship table corresponding to second level of indication
[0125] For example, there is only one level of indication in a first signal, and the mapping relationship table corresponding to this level of indication is shown in Table 3.
[0126] Table 3: Mapping relationship table corresponding to first level of indication
[0127] B12022, the mapping relationship between the value of the code point and whether the second device starts the timer on the second serving cell is determined based on the code point index corresponding to the value of the code point, the target index, and the number of active serving cells associated with the first signal; the target index is an active serving cell index or an active serving cell group index.
[0128] In some embodiments, in one implementation, the specific implementation of determining the mapping relationship between the value of the code point and whether the second device starts the timer on the second serving cell based on the code point index corresponding to the value of the code point, the target index, and the number of active serving cells associated with the first signal includes:
[0129] Formula one, Sequence_index = round(A_index / N) mod N;
[0130] Wherein, Sequence_index represents the code point index; A_index represents the target index; N represents the number of active serving cells associated with the first signal.
[0131] For example, the number of active serving cells associated with the first signal is 2, and 3 sequences are needed to indicate all combinations, as shown in Table 4.

[0134] B21, single-level sequence, indicating that the second device starts or does not start a timer on the second serving cell by the index of one sequence;
[0135] For example, the first device determines the sequence index (Sequence index) of the active serving cell associated with the first signal according to a predetermined rule; for example, 6 active serving cells are associated with the first signal, and a total of 64 sequences are needed, and the correspondence between sequence_index and the active serving cell identifier associated with the first signal is shown in Table 5.

[0144] B15, a monitoring position parameter of the first signal;
[0145] In some embodiments, the monitoring position parameter includes but is not limited to at least one of the following: bit position, Orthogonal frequency division multiplex (OFDM) symbol index, OOK symbol index.
[0146] In some embodiments, in the case where the second serving cell includes at least one active serving cell configured for the second device, the active serving cell associated with the first signal is obtained by at least one of the following:
[0147] C11, a high-layer parameter configuration;
[0148] In some embodiments, this case refers to that the active serving cell associated with the first signal is configured for the first device by the network device through a high-layer parameter. For example, the high-layer configures a set of associated cells when configuring the first signal; for example, taking the first signal as an LP-WUS, the high-layer configures the indexes of the LP-WUS#0 associated cell or cell group as 0 and 3, configures the indexes of the LP-WUS#1 associated cell or cell group as 1 and 4, and configures the indexes of the LP-WUS#2 associated cell or cell group as 2 and 5.
[0149] C12, obtaining based on the index of the first signal, a target index, and the number of the first signals, the target index being an active serving cell index or an active serving cell group index;
[0150] In some embodiments, in one implementation, the obtaining of the active serving cell associated with the first signal based on the index of the first signal, the target index, and the number of the first signals includes:
[0151] Formula two, P_index=A_index mod(M);
[0152] Wherein, P_index represents the index of the first signal, A_index represents the target index, and M represents the number of the first signals in time division multiplexing.
[0153] In some embodiments, the implementation of receiving the first signal on the at least one first serving cell comprises:
[0154] Periodically monitoring the first signal in a first time window on the at least one first serving cell;
[0155] Wherein, the first time window is determined based on an offset value and a minimum time interval, the offset value is used to indicate the length of time that the first time window is located before a reference point, and the reference point is the start time of the timer; and the minimum time interval is determined based on the processing capability of the second device.
[0156] For example, as shown in FIG. 5, the timer is started at T1, and T2 is the end time of the first time window, wherein the time difference between T2 and T1 is the length of time indicated by the minimum time interval, and T3 is the start time of the first time window, wherein the time difference between T2 and T1 is the length of time indicated by the offset value. In some embodiments, the units of the offset value and the minimum time interval in the embodiments of the present disclosure can be, but are not limited to, seconds (s), milliseconds (ms), slots, symbols, frames, and subframes.
[0157] In some embodiments, the offset value and the minimum time interval can be configured by a higher layer.
[0158] In some embodiments, the period of the first signal can be configured by a higher layer, and the period of the first signal satisfies at least one of the following conditions:
[0159] D11, independent of the discontinuous reception cycle, i.e., the period of the first signal is independent of the discontinuous reception cycle, i.e., the period is a period dedicated to the first signal;
[0160] D12, related to the discontinuous reception cycle, i.e., the period of the first signal is configured based on the discontinuous reception cycle; for example, the period of the first signal can be a multiple of the discontinuous reception cycle.
[0161] In some embodiments, the first device can periodically receive the first signal or non-periodically receive the first signal. That is, the first signal received by the first device can be periodic or non-periodic, and the receiving behavior of the first device depends on the sending behavior of the network device, i.e., how the network device sends, and the first device adopts the corresponding way to receive.
[0162] In some embodiments, in an implementation where the second serving cell comprises at least one of the activated serving cells configured for the second device, the receiving the first signal on the at least one first serving cell comprises:
[0163] The receiving the first signal on the at least one first serving cell is performed by time division multiplexing (TDM), frequency division multiplexing (FDM) or code division multiplexing (CDM).
[0164] For example, the first signal can be transmitted on multiple first serving cells by FDM, or the first information can be transmitted on one first serving cell by TDM.
[0165] In some embodiments, in an implementation where the second serving cell comprises any of the activated serving cells configured for the second device, and the second serving cell is the same as the first serving cell, the method further comprises:
[0166] If the first device does not receive the first signal on the first serving cell, one of the following is performed:
[0167] E11, starting the timer;
[0168] E12, not starting the timer;
[0169] E13, the behavior of whether to start the timer on the second serving cell is consistent with the behavior of whether to start the timer on the primary cell of the second device;
[0170] For example, the second device starts the timer on the primary cell, and if the first device does not receive the first signal on the first serving cell, the first device determines that the second device also starts the timer on the first serving cell.
[0171] E14, the behavior of whether to start the timer on the second serving cell is consistent with the behavior of whether to start the timer on the activated secondary cell with the largest or smallest number of the second device;
[0172] For example, the second device is configured with 5 activated secondary cells, and the determination of whether to start the timer on the secondary cell 1 is performed, for example, the second device does not start the timer on the secondary cell 1, and if the first device does not receive the first signal on the first serving cell, the first device determines that the second device also does not start the timer on the first serving cell.
[0173] The following takes the first device and the second device as an example, and the first device receives the LP-WUS sent by the base station. The specific application of the embodiment of the present disclosure is illustrated as follows.
[0174] Application case one: the LP-WUS on one serving cell indicates whether the second device starts the timer on all activated serving cells, corresponding to the above application scenario one.
[0175] Specifically, the main implementation process on the base station side includes:
[0176] Step S111, the base station configures a serving cell set for at least one terminal;
[0177] The serving cell set is all activated serving cells of the terminal, for example, the serving cell set includes a primary cell, a plurality of secondary cells (or a plurality of secondary cell groups (Scell group)).
[0178] For example: serving cell set = {Pcell, Scell group#1, Scell group#2, Scell group#3, Scell group#4}.

[0183] The indication mode includes at least one of the following:
[0184] Bitmap, that is, 1 bit is used to indicate whether the timer is started on all activated serving cells in the serving cell set of a first device.
[0185] For example: LP-WUS = [1 0 1 0] indicates that the timer is started on all serving cells in the corresponding serving cell set of UE1 and UE3; the timer is not started on all serving cells in the corresponding serving cell set of UE2 and UE4.
[0186] Code point, that is, the value of 1 code point is used to indicate whether the timer is started on all activated serving cells in the serving cell set of a UE or a plurality of UEs.

[0192] P15, a monitoring location parameter of the LP-WUS, including but not limited to at least one of: a bit position, an OFDM symbol index, and an OOK symbol index.
[0193] Step S113, the base station determines a first serving cell;
[0194] In some embodiments, the first serving cell can be determined in one of the following ways:
[0195] Way 1: protocol specification, i.e., determining the first serving cell as a primary cell or a secondary cell or a secondary cell group based on protocol agreement;
[0196] Way 2: determining according to the receiving capability of the first device reported by the terminal.
[0197] In some embodiments, in the case where the base station determines the first serving cell based on the receiving capability of the first device reported by the terminal, the base station can indicate the first serving cell to the terminal through signaling, and in some embodiments, the base station can indicate the first serving cell to the terminal through MAC-CE, high layer parameters, or DCI.
[0198] In some embodiments, the first serving cell can be a primary cell or a secondary cell.
[0199] Step S114, the base station periodically or aperiodically transmits the LP-WUS on the first serving cell;
[0200] In some embodiments, if the base station periodically transmits the LP-WUS, the period of the LP-WUS can be independent of the discontinuous reception cycle configuration, or can be related to the discontinuous reception cycle.
[0201] Specifically, the terminal side mainly implements the following procedures:
[0202] Step 121, the first device periodically or aperiodically receives the LP-WUS on the first serving cell in the serving cell set;
[0203] In some embodiments, if the LP-WUS is received periodically, the first device can acquire the period of the LP-WUS through at least one of the following: a broadcast signal (SIB, PBCH), a predefined manner, a high layer configuration, and a DCI indication.
[0204] Step 122, the first device decodes the LP-WUS according to the configuration parameters to obtain the indication information, which indicates whether to start or not to start the timer on all active serving cells in the serving cell set, i.e., it can also be understood as indicating whether to listen to the PDCCH or not to listen to the PDCCH on all active serving cells in the serving cell set.
[0205] For example, the indication manner is one of the following:
[0206] bitmap, i.e., indicating whether to start the timer on all active serving cells in the serving cell set of the first device through 1 bit.
[0207] For example: LP-WUS = [1 0 1 0] indicates that the timers on all serving cells in the corresponding serving cell set in UE1 and UE3 are started; the timers on all serving cells in the corresponding serving cell set in UE2 and UE4 are not started.
[0208] codepoint, i.e., indicating whether to start the timer on all active serving cells in the serving cell set of one UE or multiple UEs through the value of 1 codepoint.
[0209] For example, the bitmap is shown in FIG. 6, indicating that the timers on all active serving cells in the serving cell set of UE1 and UE3 are started; the timers on all active serving cells in the serving cell set of UE2 are not started.
[0210] For example, the behavior of 4 UEs is indicated through the codepoint, as shown in Table 8:
[0211] Table 8: Correspondence between codepoint and indicated UE starting timer
[0212] Step 123, the first device indicates to the second device whether to start or not to start the timer on all active serving cells within the serving cell set, so as to perform the behavior of monitoring or not monitoring the PDCCH.
[0213] Application case two, the LP-WUS on one serving cell indicates whether the second device starts the timer on all active serving cells or part of the active serving cells, corresponding to the above-mentioned application case two

[0216] The serving cell set is all active serving cells of the terminal, for example, the serving cell set includes a primary cell, multiple secondary cells (or multiple secondary cell groups (Scell group)).
[0217] For example: serving cell set = {Pcell, Scell group#1, Scell group#2, Scell group#3, Scell group#4}.
[0218] Step 212, the base station configures the configuration parameter for at least one terminal;
[0219] The configuration parameter includes at least one of the following:
[0220] P21, the payload size of the LP-WUS;
[0221] P22, the indication mode of whether to start the timer;
[0222] bitmap, that is, one bit indicates whether one or more active serving cells start the timer; for example, under this indication mode, it can include two indication cases: indication case one, one bit indicates whether to start the timer on all active serving cells included in the second serving cell at the same time; indication case two, multiple bits respectively indicate whether to start the timer on the active serving cells included in the second serving cell, and whether to start the timer on different active serving cells can be the same or different.
[0223] codepoint, i.e. the value of 1 codepoint indicates whether one or more serving cells start the timer or not; for example, in this indication mode, there are two indication cases: indication case one, 1 codepoint indicates that the activated serving cells included in the second serving cell start the timer or not; indication case two, multiple candidate codepoints indicate whether the activated serving cells included in the second serving cell start the timer or not, and the behaviors of whether the activated serving cells start the timer or not can be the same or different.

[0227] Step 213, the base station determines the first serving cell;
[0228] For specific implementation, please refer to application case one, which will not be repeated here.
[0229] Step 214, the base station determines the second serving cell associated with the LP-WUS, i.e. determines one or more activated serving cells associated with the LP-WUS;
[0230] In some embodiments, the association between the one or more activated serving cells and the LP-WUS can be achieved by:
[0231] P_index=Cell_index mod(M), or, P_index=Cellgroup_index mod(M);
[0232] Wherein, M represents the number of TDM LP-WUS, P_index=0~M-1; Cell_index represents the activated serving cell index, Cell_index=0~X1, X1 is the number of activated serving cells, Cellgroup_index represents the activated serving cell group index, Cellgroup_index=0~X2, X2 is the number of activated serving cell groups.
[0233] Step 215, the base station transmits the LP-WUS periodically or aperiodically on at least one first service cell according to a specific indication mode.
[0234] Specifically, the main implementation process on the terminal side includes:
[0235] Step 221, the first device receives the LP-WUS periodically or aperiodically on the first service cell in the service cell set;
[0236] In some embodiments, the terminal can monitor multiple LP-WUS on at least one first service cell through TDM, FDM or CDM.
[0237] Step 222, the first device decodes the LP-WUS according to the configuration parameters to obtain the indication information, which indicates whether to start or not to start the timer on at least one active service cell configured for the second device, that is, it can also be understood as indicating whether to monitor or not to monitor the PDCCH on at least one active service cell configured for the second device;
[0238] For example, the specific indication mode is one of the following:
[0239] Indication mode 1 includes one of the following:
[0240] bitmap: 1-bit indicates the same PDCCH monitoring behavior of the active service cells in the first associated cell set; for example, bitmap: 1-bit indicates the same PDCCH monitoring behavior on multiple cells, as shown in FIG. 7, the timer is started on the cells with Cell_index of 0, 3, 1 and 4; the timer is not started on the cell with Cell_index of 2.
[0241] codepoint: 1 codepoint indicates the same PDCCH monitoring behavior of the active service cells in the first associated cell set.
[0242] Indication mode 2 includes one of the following:
[0243] Bitmap: multiple bits respectively indicate whether to start or not to start the timer on the active service cells in the first associated cell set, and the behavior of whether to start the timer on different cells can be the same or different, for example, as shown in FIG. 8, two bits are used to respectively indicate the behavior of whether to start the timer on each cell, in FIG. 8, the timer is started on the cells with Cell_index of 3, 1 and 4; the timer is not started on the cells with Cell_index of 0 and 2.
[0244] Codepoint: multiple candidate codepoints indicate whether to start the timer on each active service cell included in the second service cell.
[0245] Case three, the LP-WUS on one serving cell indicates whether to start the timer for the second device on the serving cell, corresponding to the above-mentioned application scenario three
[0246] Specifically, the main implementation process on the base station side includes:
[0247] Step 311, the base station configures a serving cell set for at least one terminal;
[0248] The serving cell set is all active serving cells for the terminal, for example, the serving cell set includes a primary cell, multiple secondary cells (or multiple secondary cell groups (Scell group)).
[0249] For example: serving cell set = {Pcell, Scell group#1, Scell group#2, Scell group#3, Scell group#4}.
[0250] Step 312, the base station configures the configuration parameters for at least one terminal;
[0251] The configuration parameters include at least one of the following:
[0252] P31, the payload size of the LP-WUS;
[0253] P32, the indication mode of whether to start the timer;
[0254] The indication mode includes at least one of the following:
[0255] bitmap: 1-bit indicates whether to start the timer on one serving cell;
[0256] codepoint: the value of 1 codepoint indicates whether to start the timer on one serving cell;

[0258] P34, the time-frequency resource mapping mode of the LP-WUS, including but not limited to one of the following: OOK-1 based on M = 1, 2, 4, 8, 16, 24 or 32, OOK-4 based on M = 1, 2, 4, 8, 16, 24 or 32.
[0259] Step 313, the base station periodically or aperiodically sends the LP-WUS on the first serving cell;
[0260] In some embodiments, if the base station periodically transmits the LP-WUS, the period of the LP-WUS can be independent of the discontinuous reception cycle configuration, or can be related to the discontinuous reception cycle.
[0261] Specifically, the terminal side mainly implements the following procedures:
[0262] Step 321, the first device receives the LP-WUS on the first serving cell;
[0263] The first serving cell can be any cell in the serving cell set.
[0264] Step 322, the first device decodes the LP-WUS according to the configuration parameter to obtain the indication information, which indicates whether the second device starts or does not start the timer on the first serving cell, that is, it can also be understood as indicating whether the second device listens to the PDCCH or does not listen to the PDCCH in the first serving cell;
[0265] For example, the meaning of the indication information can be one of the following:
[0266] Meaning 1: indicating not to start the timer;
[0267] Meaning 2: indicating to start the timer.
[0268] In some embodiments, the second device performs a corresponding behavior on the first serving cell according to the meaning of the indication information; specifically, when it is meaning 1, the second device does not start the timer on the first serving cell, that is, does not perform PDCCH listening; when it is meaning 2, the second device starts the timer on the first serving cell, and performs the behavior of PDCCH listening or not.
[0269] In this case, it can be understood that the first device receives the LP-WUS on each Pcell and each Scell respectively, indicating whether the second device starts the timer on the corresponding cell. For example, as shown in FIG. 9, the second device starts the timer on the Pcell, Scell#1 and Scell#3, and does not start the timer on the Scell#2.
[0270] It should be noted that at least one embodiment of the present disclosure realizes that the MR receives the LP-WUS through the LP-WUR to indicate the energy saving behavior of the MR on the activated serving cell, improves the flexibility of the network side, and reduces the bit overhead in the case of guaranteeing the energy saving performance.
